Axle Replacement Recommendation for Trailer with 4 on 4 Bolt Pattern Hubs

Question:

Ok so the axle on my trailer measure 64 1/2” from the center to center on the first photo. The measurements from the flange outside to outside measurements are 82 7/8”. The spacing from the frame to center of hanger hole is 2 1/2” in front and 4” in back. I’m not quite sure what weight this axle is but would like to replace and put in a tandem axle, in order to compensate the weight for what I’m building. What axle set along with additional parts would you reco

As far as a straight axle goes we do not have one that is an exact match for the measurements you have provided. If you wanted a straight axle it would have to be a custom order from a local place. What I recommend instead is to go with a Timbren Axle-Less system which can be used in a tandem set up.

The Timbren systems will also replace the suspension with rubber springs that will hold up and function better compared to leaf springs. They are available from capacities of 1,200 pounds to 7,000 pounds per set. I have included a link to the options for you. If you can tell me the diameter of your existing axles I can estimate the capacity. The bearing numbers in the hub are also useful in determining axle capacity. And there may be a tag on the axle or capacity information stamped into it as well.
